Summary:The present invention relates to a method for setting the routing in software defined networks, and a device thereof. According to an embodiment of the present invention, the method comprises the steps of: measuring a delay time of a packet loop including a flow path through test packet transmission having a time-stamp marked thereon, wherein the packet loop includes the flow path, and means the shortest loop path from a routing setting device to the routing setting device; measuring a unidirectional delay time of the flow path by using edge switch information corresponding to the flow path; and determining whether a routing flow is reset or not based on the measured unidirectional delay time.
